IMPROVEMENT IN BARREL-MACHINES.

Specification forming part of Letters Patent No. 5195.185, datedSeptember 11, 1877; application filed August 24, 1877.

To all whom it may concern Be it known that I, JAMES TOMLINSON, otGoderich, in the county of Huron, and Province ofOntario, Canada, haveinvented an Improvement in a Machine for Making Barrels and othercylindrical packages, of which the following is a specification:

My invention has relation to the manufacture of that variety of barrelsand similar packages wherein the cylindrical body is formed or built upof two layers of wood-veneers, so disposed as to cross the direction oftheir respective grains.

The object I have in view is to provide a single machine with which thebody may be formed and held while the hoops are run on and fastened,and, also, by means of a pair of circular saws, to equalize the ends ofthe tin ished body. To this end, my invention consists, mainly, in aslotted sheet-metal cylinder or former, over which the body is formedand arranged to collapse, so as to permit the fin ished body to bewithdrawn; also, in combination with a rotating collapsible former, aseries of guides in a swinging frame, and a guiding press-roll journaledtherein for directing the hoops upon the body, and to compress the wholeupon the former until all the parts are firmly secured together 5 also,in combination with the said rotating former, a pair of circular cut-offsaws, mounted on the ends of an arbor rotating in a vibrating frame,forequalizing the ends of the completed body; and in the generalconstruction and arrangement of the various parts, as more fullyhereinafter set forth.

Figure 1, Sheet 1, is an end elevation, with a portion of the head ofthe former broken away. Fig. 2 is an elevation of the clamp. Fig. 3 is aplan of the press-roll. Fig. 4. is a front elevation of the machine.Fig. 5, Sheet 2, is a plan view. Fig. 6 is an enlarged end elevation ofthe forming-drum. Fig. 7 is a longitudinal section of the same at g g,Fig. 6.

In the drawings, A represents the base of the machine, upon one end ofwhich two standards, B B, are erected, and through which a shaft, 0, isjournaled, and provided with fast and loose pulleys, so as to be rotatedby belts from a counter-shaft, 0, below.

D is a drum or cylinder, of sheet metal, mounted on heads D D mounted onthe overhanging end of the shaft O. The drum D is longitudinally slottedor cut from end to end, and one edge or end is not secured to the heads,so that, being elastic, it can be sprung. inwardly, or partiallycollapsed, (the corresponding parts of the heads being cut away for thatpurpose,) so as to permit of the withdrawal of the finished body.

E is a frame, whose foot is pivoted by arock-shaft,a,,tothespring-leverA. Atreadle, b, at the end of therock-shaft, engaging with an adjacent ratchet, 1), serves, throughacord, 0, attached to the said shaft and toa girt of the frame, to drawup the latter and secure it in a vertical plane.

A is a spring attached to the frame A, and serves, in connection witharatchet, 1), springlever A, cord 0, and lever b, to hold the pressrollin a rigidly yielding condition while the veneers are being wound on thedrum, and thereby allowing the roll to rise under pressure when andafter the second layer of veneer is inserted.

The frame has a bracket at one end, which comes under and supports theoverhanging end of the shaft 0 when the frame is swung into position.

F is a press-roll, journaled in the frame E, which is slotted Where therock-shaft a passes through it, to allow a limited vertical play of theroll as the work passes between it and the drum. This press-roll has aseries of grooves, d, each of which receives a hoop and presses it toplace on the barrel.

On a girt of the frame E a series of curved shoe-guides, e, is secured,one in line with each groove d in the press-roll. A roller, 0, istransversely pivoted in each shoe, and under it the hoop passes whilebeing guided to the press-roll.

A folding press-bar, G, is pivoted to a pair of brackets on the frontside of the frame E, whose function is to bend down the veneersheet asit goes onto the drum.

The drum is normally expanded into a true cylinder, from which it wouldnot be easy to remove the finished barrel-body. It is, therefore, madeto collapse to permit the withdrawal of the body. The heads D eachinclose a little more than half the end, while nearly all the rest hasfastened in it a crescent-shaped head, D each of which is connected onthe inside, by a link,f, with an eccentric, G, journaled in the heads D,and which eccentric-shaft may be rotated by an external lever, g, tothrow out or retract the free part of the cylinder-body.

Just inside the stationary lip of the cylinder there is a clamp-bar, h,with an inwardlyturned arm at each end, that is pivoted to a lever, i,pivoted on the outside of each head By means of these levers theclamp-bar may be thrown forward to compress the edge of a sheet ofveneer against the lip of the cylinder, where it is held by engaging thelong armof each lever with a spring-catch, 'i.

H is a frame, whose foot is pivoted to the base behind the drum. On eachend of an arbor, journaled through said frame, a circular saw, I, ismounted, and the arbor is arranged to be driven, when the saws are movedtoward the drum, so as to cut off or equalize the pro jecting ends ofthe body.

The barrel is made in two layers or thicknesses of veneer. The inner oneis a single sheet, disposed with the grain circumferential to the axisof the barrel, while the outer thickness may be in two or more sheets,whose grain runs parallel with the axis.

The modus operandt' is as follows: The sawframe is thrown back, asrepresented in dotted lines in Fig. l. The press-roll frame is alsothrown into the vertical position over the drum, whose clamp-bar isretracted. A sheet of veneer is then introduced in the slot of the drumand clamped fast. The drum is then rotated about one-quarter of arevolution, the sheet bending around closely as it passes under thepress-roll. An outer stave is then laid on, and the drum rotated untilit has passed behind the press-roll. A set of hoops, k, Fig. 1, are thenlaid in the guides and passed through the grooves in the press-roll andonto the second sheet, and nailed fast to both sheets, the ends of thenails being clinched on the iron drum. The drum is again rotated, andarrested when the edge of the stave is under the press-roll, when asecond stave-sheet is introduced and laid against the edge of the firstone, nailing each stave-sheet through the hoops and along the edges asit passes behind the press-roll.

This process is continued until the inner sheet is entirely covered bythe outer thickness of the stave-sheet, when the ends of the hoopsareoverlapped and nailed through and through. The equalizing-saws arethen brought into requisition to trim off the projecting ends of thebody, which is rotated with the drum during the process. The end of theinner sheet is then unclamped and the pressroll frame retracted, asshown in dotted outline in Fig. 1. The eccentric-shaft is then rotatedso as to partially collapse the drum, as shown in dotted outline in Fig.6, when the body of the barrel may be withdrawn from the drum. I

In order to secure the ends of the hoops and the edge of the firststave-sheet in position until the barrel is completed, a clamp-bar, J,Fig. 2, is dropped over them and hooked under the ends of the drum,where it is left until the free ends of the hoops are ready to be lappedand fastened.

With one man and two boys a barrel-body can be completed in every sixminutes.

It is not essential to have the press-roll frame made to swing asdescribed, as it is evident thatsaid press-roll can be placed in a fixedsupport above the drum, and be pressed down by a superposed spring.

What I claim as my invention is 1. A collapsible drum, substantially asdescribed, in a barrel-machine, in combination with the rigidly-yieldinggrooved press-roll F, cord 0, lever b, ratchet b, and spring-lever A,for the purpose set forth.

2. In a barrel-forming machine, substantially as described, thecombination of the press-roll and a series of hoop-guides with thecollapsible rotary drum, substantially as set forth.

3. In a barrel-forming machine, substantially as described, thecombination of the equalizing-saws and their swinging frame with therotary collapsible drum, substantially as described.

4. In a barrel-machine, the clamp J, in combination with a collapsibleforming-drum, substantially as described, for the purpose set forth.
